After searching and searching and not finding a NOS AC Delco optispark for my 93, iīm torn between a Petris optispark and the Delphi one that is posted on ebay and the seller says it is new.
I know the first one is vented and claimed to has the Mitsubishi optical sensor; also i read a lot on the internet about Mr. Petris (mostly good), but someone has experience with this distributor?
Does the Delphi distributor has the Mitsubishi optical sensor? The seller couldnīt answer that....
Someone using it?
On the other hand, i donīt trust in the remanufactured Ac Delco optisparks posted all over the internet.
As i live outside US, itīs not easy to return a part.
thanks in advance

Here we go.

Here are pics of a Petris disassembled









The grinding and debris were in there when I opened it. This has less than 5 minutes runtime on it. Never even got it out of park before pulling it off.

I put a chandlers unit on 2years ago, I run hard and it's doing great. Paid $137 for it

You should recheck the wording from Petris. Last I checked it said "Mitsubishi quality sensor" or something to that effect. Essentially it's an over priced cheap part store opti. Of those two choices I would go with Delphi. The chandler opti sounds interesting. I have heard good things about it, though I have no experience with it.

I just found a new ac delco (not a NOS).
Corvette America has it and they confirm that is a new delco distributor.
Itīs probably the same part that delphi with other brand. maybe.....
I īll go for one of those two.
thanks
